php - Parsing JSON when multiple arrays returned in Objective C -

i trying parse json returned following link:

https://icansolvecouk1.fatcow.com/prco303/loginjson.php?nickname=maggie&password=maggie

which is:

[{"sent":"2013-05-12 09:32:14","sender":"1","recipient":"1","message":"hey hey hey"},{"sent":"2013-05-12 16:39:02","sender":"2","recipient":"1","message":"another message"}] 

using following code in obj-c:

nsdictionary *user = [result json]; nslog(@"nsdictionary returned: %@",user); nsarray* arrayofreturneditems = [user objectforkey:@"message"]; nslog(@"array returned: %@",[arrayofreturneditems objectatindex:0]); 

nsdictionary stores json value errors occur later on. new obj-c , json appreciated. checked on jsonlint.com says valid believe reason errors getting pulling 2 arrays (from url) not parsing correctly. have access server serving json perhaps need make change there?

spent half day searching site before went ahead , asked i'll result!

thanks

this line:

nsdictionary *user = [result json]; 

should be:

nsarray *users = [result json]; 

then need process each of (or 1 of) dictionaries in array.

next, message you're trying extract string (nsstring), you're code says array you'll have problems there too.

you may find useful log class of items check think things are:

nslog(@"class or user:%@", nsstringfromclass(user));
